RAYMOND H. HORNBROOK, OF CANTON, OHIO/ BRAKE-BEAM.

SPECIFICATION forming part of Letters Patent No. 725,709, dated April 21, 1903.

Application filed June 20, 1902.

To all whom, it may concern:

Be it known that I, RAYMOND H. HORN- BROOK, a subject of theKing of Great Britain, residing at Canton, in'the county of Stark and State of Ohio, have invented a new and useful Brake-Beam, of which the following is a specification.

My invention relates'to a trussed brakebeam, and has for its objects a simple but efficient construction with an angle-bar for the compression member, a rod for the tension member, and an arrangement by which. the parts are secured together in'a positivemanner. I-attain these objects by the construction and arrangement illustrated in the accompanying drawings, in which- Figure 1 is a plan View of the brake-beam, showing one head in section; Fig. 2, an inner side View of the same; Fig. 3, a detached side view of the fulcrum; Fig. 4, a detached inner end view of the same; Fig. 5, a detached plan View of the same, and Fig.6 a detached inner side view of one beam-head.

Similar numerals refer to similar parts throughout the drawings.

The brake-beam is composed of the anglebar compression member 1, the rod tension member 2, the cast fulcrum 3, which separates the bar and the rod in the middle, the similar cast-heads 4, respectively receiving the ends of the bar and rod, and the nuts 5 on the respective ends of the rod, which bind the parts together. The compression angle-bar is preferably located with its open or concave side directed inward toward the tension-rod. The bar is slightly bent in the middle at its bearing in the head 6 of the fulcrum, from which it is inclined either way-to join the tension-rod in the sockets 7 in the respective heads of the beam. The tensionrod is preferably round and is also slightlybent in the middle at its bearing between the legs 8. of the fulcrum, from which it is inclined either way to join the angle-bar in the respective beam-heads. The rod is extended either way beyond the ends of the angle-bar through the perforations 9 in the respective beam-heads and receives the respective nuts 5 on its projecting ends on the outer sides of said heads. The fulcrum is composed of the head 6 on one end, the usual side plates 11,

filerial no. 112,400. (No as.)

' between which is pivoted the ordinary brakelever(not shown) in the middle, and the legs 8 on the other end. The fulcrum-head is composed of the lower outer jaw 13, which is inclined upward and outward, and the upper inner jaw l4,-which is inclined downward and outward, between which jaws the angle-bar is inserted, as shown in section in Fig. 2. The inner face of the lower jaw joins the outer side of the lower flange of the anglebar, and the outer face ofv the upper jaw joins the inner. side of the upper flange. The free edge'of the upper jaw and the free edge of the longitudinal web or partition 15, which connects the upper jaw with the base of the lower jaw,-join the inner side of the lower flange of the angle-bar.

The angle-bar is preferably secured by rivets 16 to the upper jaw on either side of the Web 15, and the joining faces of the respective jaws are inclined to conform to the which notchreceives and holds in place the tension-rod.

The beam-heads are provided with the sockets 7 in their respective inner sides, which sockets are shaped in cross-section to neatly receive the respective end parts of the anglebar, and the bottoms of the sockets abut squarely against the respective ends of the bar. The perforations 9 for neatly receiving -the tensionbars are also provided through the respective beam-heads, and the outer faces 18 of the respective heads are inclined to be perpendicular to the axis of the tension-rod at its respective ends, which inclined faces squarely receive the respective nuts 5.

The parts are so arranged that the nuts are opposite the respective ends of the compression-bar, so their force'when turned on the ten sion-rod is exerted directly against the respective ends of the bar, thus insuring a positive binding of all the parts of the beam. The sides of the beam-heads are respectively formed in the usual manner for receiving and attaching the ordinary brake-shoes. (Not shown.)

In the arrangement of the angle-bar and beam-heads as illustrated the tension-bar passes between the respective flanges of the a is directed toward the tension-rod without affecting the general nature of my invent-ion.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. A brake-beam composed of an angle-bar compression member, a rod tension member, a separating-fulcrum having jaws on one end embracing the outer face of the lower flange and abutting against the inner faces of both flanges of the angle-bar, and a notch in the other end to receive the rod, heads receiving the ends of the angle-bar and the rod, and nuts on the ends of the rod.

2. A brake-beam fulcrum having a jaw inolined upward and outward from the lower side of one end, and a jaw inclined downward and outward from the upper side of said end, said jaws being adapted to join the outer side of the lower flange and the inner sides of the flanges, respectively, of an-angle-bar.

, 3. Abrake-beam fulcrum having a jaw inclined upward and outward from the lower side of one end, a jaw inclined downward and outward from the upper side of said end, and a web connecting said upper jaw with the base of said lower jaw; the lower jaw being adapted to join the outer side of the lower flange, the upper jaw being adapted to join the inner side of the upper flange, and the free edges of the upper jaw and the web being adapted to join the inner side of the lower flange, respectively, of an angle-bar.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

I RAYMOND H. HORNBROOK.
